I have a Lenovo G580 Intel core i3 with intel HD graphics 4000, so i bought titanfall thinking it would run good (so wrong) and i'm looking to upgrade my GPU not just for this game but for some in the future cause i tend to play more on my laptop. Questions:
1. Do i need to upgrade my CPU to get a new GPU?
2. Am i even really able to replace the GPU unless its externally? and how would that even run
3.What GPU would be best for this laptop
